harvesting grain

It's harvest time in the small villages between Wuxi and Changzhou.  We were lucky to experience this as we rode through them.  On our way their, many farmers were busy cutting and stacking grain. Every driveway was covered up by rows of grain waiting to be ground and put into bags.  On the ride back, their was a lingering cloud of white smoke in the air.  This was because, after harvest, the fields are burned to add nutrients back to the soil and make it easier for planting the next crop.
